Abstract: 6522. Robertson, P. L. March 15. Turning wood-screws. -In a wood-screw machine in which the head is shaved, simultaneously with the threading of the shank, by a tool mounted in the chuck, the head-shaving tool is moved axially and transversely into engagement with the head. The shaving-tool 135, Figs. 8 and 12, is in the form of a flat bar slidable in a groove in a rod 139 extending through the chuck spindle, and is actuated by a cam-operated lever engaging between lugs 143, the fulcrum of the lever being adjustable. The transverse movement of the tool is obtained by a cam 163 on a collar 160, adjustably connected to the rod 139 by a screwed rod 166. Lubricant is supplied to the head-shaving tool by a tube passing axially through the rod. The threading- tool 200, Fig. 19, is traversed by a cam 250 secured to a slide block 253 which engages a resilient strap 255 connected to an arm 256 on the rocking shaft 202 which carries the threading-tool, this connexion allowing the tool to be swung outwards on the completion of the threading operation. The back-rest 127<1>, Fig. 7, is carried by a lever 127 and is moved into engagement with the blank against spring return by an arm 128 which carries a wedge-adjusted finger 128<1> and is connected to cam-operated goose-neck lever 132. The blank feeding; chucking and headstock-driving means; and the means for adjusting the threading-tool are described in Specifications 19,574/11, 19,575/11, and 440/12.

Title: Improvements in the Manufacture of Diolefines.
Inventor: JOHNSON JAMES YATE
IPC: C07C1/30
Filed: 1911-05-04
Granted: 1912-05-06
Abstract: 10,826. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. May 4. Diolefines; caoutchouc; methylisopropyl ketone. -Diolefines, some of which may be employed in the production of caoutchouc, are produced by treating dihalogenparaffins, monohalogenalkylenes, and monohalogen monohydric alcohols, with barium chloride, nickel chloride, lead chloride, alumina, or caustic lime, whereby halogen hydride or halogen hydride and water is split off. In examples, trimethylethylene bromide on treatment with barium chloride yields isoprene, which can also be obtained from trimethylethylene chloride, 2 4-dibrom-2-methylbutane, and 3:4-dibrom-2-methylbutane in a similar manner; 2:3-dibrombutane yields butadiene; trimethylethylene bromide and 2:4-dibrom-2-methylbutane on treatment with caustic lime yield isoprene; 3-brom-2-methylbutene on treatment with caustic lime yields dimethylallene; trimethylethyleneglycol chlorhydrin on treatment with alumina yields isoprene and methylisopropylketone; and 3-brom-2-methylbutene-(2) on treatment with alumina yields isoprene. The above processes may be carried on under diminished pressure. 2:4-Dibrom-2-methylbutane is produced by the action of hydrobromic acid upon dimethylallene.

Brushes mounted as shown in Fig. 3 supply current from a source on the train to the left-hand wire b, and collect current from the right-hand wire and from the contacts d‹, c', &c. to actuate signals or to energize a magnet which removes a detent from a brake valve if two trains approach too closely. At junctions, the conductors are suitably connected by a switch operated in connexion with the points-blades. Audible signals at level crossings &c. may be given, or lamps may be lighted from the line wires. The current collector, Fig. 3, comprises a wire brush z or trolly or the like supported on a pin y in a rod x carried by a spring v attached to a bracket u. This bracket u is slotted to guide the top end of the rod x, and is adjustable in guides u<1> fixed to the frame of the vehicle. A pair of trollies may be connected by their axles. If more than one train is on a section at a time, those behind the first have the batteries disconnected, and the left-hand brush joined to the signalling- apparatus.

Abstract: 26,374. Fraser, J. J. Nov. 25. Plastic compositions containing oxychlorides. -In the covering of walls, floors, &c. with panels &c. of artificial stone, the surface to be covered is cleaned, and a composition consisting of about 75 per cent of pitch, 15 per cent of Portland cement, 7 per cent of pulverized slag, stone, or gravel, and 3 per cent of creosote oil, is applied in a heated state. Panels are moulded on a glass or like plate from a composition such as that described in Specification 5079/11, but preferably having 40 per cent of slag and 36 per cent of magnesite, and when partially hardened are placed with the glass plate against the wall, the plate being removed when the plate hardens.

Title: Improvements in Valves and Valve-operating Mechanism for Controlling the Intermittent Discharge of Liquids in Sewage Works, and for analogous purposes.
Inventor: BRYAN ARTHUR
IPC: E03F5/22
Filed: 1912-02-14
Granted: 1912-06-27
Abstract: 3699. Bryan, A., and Mountfort, L. F. Feb. 14. Actuating.-For supplying sewage to filter beds &c. a rotary-plug valve or similar non- reversing valve element is used, which is opened or closed by motion transmitted from a reciprocating plunger or like positively-actuated member through a one-way clutch which turns the plug by equal steps always in the same direction. In the arrangement shown, the plunger carries a rack g engaging with a toothed quadrant f, which forms the driving-member of the clutch, its motion in one direction being communicated to the driven element d by means of wedging- rollers d<2> situated in recesses on the element d, which is fixed to the spindle of the valve a. A spring catch k<1> engages in notches j<1> in a disk j keyed to the spindle and thus retains the valve in its open and closed positions. A modified form of clutch comprises a pawl on an arm attached to the quadrant, the driven part consisting of a four-toothed ratchet-wheel. The plunger may be used to open or close the valve by a single-acting hydraulic or compressed-air ram or by an electric system including a solenoid, the reverse motion being under gravity. Or a double-acting ram or a double solenoid system may be used. Where groups of valves are operated from a distant control station, hydraulic or electrical devices may be employed for amtomatically controlling the opening and closing of the valves and for regulating the timing of the operations in order to vary the duration and frequency of the discharges.
